-By default, the latest available version of the Modrinth modpack is selected based upon the value of `MODRINTH_DEFAULT_VERSION_TYPE`, which defaults to "release". Other valid values are "beta" and "alpha".

-The selected version can also be narrowed by a few means: If wanting to use a particular mod loader, set `MODRINTH_LOADER` to either "forge" or "fabric" (Quilt support is coming soon). Since the overall `VERSION` gets dictated by the modpack, a specific modpack Minecraft version can be specified by setting `MODRINTH_MC_VERSION` to a valid version, such as "1.19.2".
+The latest release or beta version, respectively, of the Modrinth modpack is selected when `VERSION` is "LATEST" or "SNAPSHOT". That can be overridden by setting `MODRINTH_DEFAULT_VERSION_TYPE` to "release", "beta", or "alpha". 
 
-A specific version of modpack file can be specified by passing the version's page URL to `MODRINTH_PROJECT`, such as <https://modrinth.com/modpack/cobblemon-fabric/version/1.3.2> or by setting `MODRINTH_VERSION_ID` to the version ID located in the Metadata section, as shown here
